NEW YORK (AP) -- If Jimmy Fallon is nervous about the premiere of his new gig as "Late Night" host, he'll have show-biz heavyweights Robert De Niro and Van Morrison to lean on.
They'll be the guests for Fallon's March 2 debut hosting the NBC late-night show.
Fallon replaces Conan O'Brien, who has his final show Friday before heading out west to take over the "Tonight" show in June.
Morrison will perform material from his critically praised "Astral Weeks" album.
NBC says Tina Fey, Jon Bon Jovi, Cameron Diaz, Drew Barrymore, Donald Trump and Serena Williams are among other guests scheduled for Fallon's first week on "Late Night."
